【Audison AF M1.7 bit｜Powerful Subwoofer Sound with a High-Quality DSP Amplifier】

Even after adding a subwoofer, the bass can sound muddy, and while you may get more volume, it doesn’t blend with the music as a whole. For issues like that, it’s important not only to have enough amplifier power, but also to make fine adjustments tailored to the vehicle interior.

Audison AF M1.7 bit is a high-performance DSP amplifier in the Audison Forza series. It combines efficient amplification using a D-class design with a DSP that operates at 24bit/96kHz—making it easier to refine not only the strength of the low end, but also the attack and definition of the sound.

It’s ideal for those who want to bring out the subwoofer’s bass firmly while also achieving a natural connection with the front speakers. You’ll get impact not only when you turn the volume up, but also at the volume you typically listen to—where the presence of the bass and kick becomes clearer, and it’s easier to add body and thickness to the overall music.

To get the most out of the AF M1.7 bit, you need to consider more than simply installing the amplifier. This includes how it connects to the vehicle’s factory audio or existing system, compatibility with the subwoofer, and even the power supply and installation method. DSP tuning also isn’t something that ends once the numbers are set. You’ll need to listen to the sound in the real vehicle and search for the points where the system naturally comes together.

If it were me, I’d first confirm what dissatisfaction you currently have with the bass in your existing system, and then consider together whether it makes sense to use the AF M1.7 bit. Rather than deciding the product first, we’ll propose a solution that includes installation and tuning—based on your vehicle model, how you use it, and the sound you prefer.
